The last few minutes are missing. For those of you who want to read what happens: (SPOILERS!)
"Having deduced that the reason the woodcutter did not speak up at the trial was because he was the one who stole the dagger from the scene of the murder, the commoner mocks him as "a bandit calling another a bandit". The commoner leaves Rashōmon, claiming that all men are motivated only by self-interest.
These deceptions and lies shake the priest's faith in humanity. He is brought back to his senses when the woodcutter reaches for the baby in the priest's arms. The priest is suspicious at first, but the woodcutter explains that he intends to take care of the baby along with his own children, of whom already has six. This simple revelation recasts the woodcutter's story and the subsequent theft of the dagger in a new light. The priest gives the baby to the woodcutter, saying that the woodcutter has given him reason to continue having hope in humanity. The film closes on the woodcutter, walking home with the baby. The rain has stopped and the clouds have opened revealing the sun in contrast to the beginning where it was overcast."
